How the data are processed

Methodology

What is included

All features in Open Database of Sports and Recreational Facilities (ODSRF), version 2.0 for Canada, using the database’s own categories (7), groups and types (54). Features whose status in the source says closed, removed, decommissioned, proposed, planned or under construction are excluded.

Names and duplicates

Only features with a usable name get a page. Features without a name, or with a placeholder such as a number or just “Park”, are counted in the totals but not listed. Trail segments with the same name in the same municipality are joined into one trail and their lengths added. When several features share a name and type in the same municipality (for example, the courts in one park), or the same name and type lie within 50 m, they are shown as one place with a count of mapped features.

Locations, lengths and areas

Source geometry is in Statistics Canada Lambert (EPSG:3347). Points are used as given. For lines, the location shown is a vertex near the middle of the longest part; for areas, it is the average of the outline’s vertices. Lengths and areas are calculated from the source geometry and corrected for map-projection scale; they are approximate. Records with coordinates outside Canada were excluded. Distances are straight-line.

Comparisons

“What stands out” compares the share of each type in the listings here with the share in Canada. Types need at least five places and a share at least 1.3 times higher. Because each municipality publishes different layers, differences can reflect data availability.

Pages that are not indexed

Place pages need at least two facts beyond name, type and location (such as an address, area or length, owner, surface, amenities, accessibility, year built or several mapped features). Pages with less are kept for navigation but marked noindex. The comparison page is also noindex.

What is not shown

No opening hours, fees, ratings, reviews, photos or descriptions are published here, and nothing confirms that a place is open or in good condition.
